Application July 29, 1935, seran No. 33,734 mmm. (ciau-'130) 'I'his invention relates to excavating machines, and more particularly to mucklng and loading machines.

The general object of the'invention is to pro' compact and easily handled, and highly efficient,

and economical in operation.

Other objects and advantages will appear herelo inafter as this specification progresses.

The invention is illustrated in the annexed drawings which form a part of this specication and in which,

Fig. 1 is a plan view vof our invention.

20 Fig.' 2 is a side elevation of our invention.

Fig. 3 is a rear elevation of our invention.

Fig.4 is a front elevation of our invention.

Referring more particularly to the drawings, in which corresponding parts are designated by the 25 same reference characters in all of the gures, our

invention comprises generally a tractor 'I a mucking shovel 2, shovel-operating means 3, an arcuate conveyor trough 4 through which said shcvel conveys the mucked dirt from in front of 30 said tractor upwardly and rearwardly to the rear of said tractor, and a discharge chute 5 leading downwardly and rearwardly from the4 rear upper end oi said conveyor trough.

Theshovel 2 is secured at its sides respectively 35 to the forward ends of a pair of swinging arms 6, which are pivotally mounted by bearings 1 at their Irear ends on the ends respectively of the rear axle 8 of the tractor I, outside the tractor treads 9 respectively.

40 On the tractor I is mounted a supporting frame I comprising a pair of uprights I I, supported at their lower ends by bearings I2 on the outerx end portions respectively of the rear axle 8 of the tractor I, between the tractor treads 9 and 45 the shovel arms 6, a cross beam I3 connecting the upper ends of said uprights I I, a pair of angle beam braces I4 connected at their rear upper ends at I to the upper-ends of said uprights II respectively and connected at their lower forward 0 ends to the ends respectively of a cross beam I6 at the forward ends of the tractor treads 9, a pair of arms I1 secured at their rear ends to the tractor frame I3 and supporting at their forward ends the cross beam` I6 which is secured nomeundersideorsamarms mapas or spaced arcuate truss bars I9 which support the conveyor trough 4 and are secured at their lower forward ends to the ends respectively of said cross beam I6, and a cross beam secured at its ends to the angle brace beams I4, over which cross 5 beam 20 extend the upper ends of said arcuate truss bars I9 and to which cross beam said truss bars are secured at their upper end portions. The conveyor trough 4 is of such length and is secured on the truss bars I9 in such position, that 10 its lower end 2I rests at a distance above the tractor I, so that the operator of the machine, sitting on the tractorseat 22, may see forwardly of the machine under said lower forward .end of said conveyor trough, while the upper end of said con- 15 veyor trough extends into the upper end of the discharge chute 5. The upper end of the discharge chute 5 is supported between the upper portions of theuprights II upon a cross beam 23 extending between and secured at its ends re- 20 spectively to said uprights, and said chute is further supported .rearwardly of said uprights by angle braces 24 secured at their lower ends to said uprights and at their upper ends to said chute.

'I'he shovel-operating means 3 comprises a 25 motor 25, a. pair of drums 26 and 21 on the shaft of said motor at the left and right' thereof respectively, sheaves 28, 29, 30 and 3|, a cable 32 wound on the drum 26 and extending over said sheaves, sheaves 33, 34, 35, and 36, vand a cable 31 wound 30 on the drum 21 and extending over said sheaves 33, 34, 35 and 36. The sheaves 28 and 33 are mounted on a pair of angle braces 23' respective- 1y. Secured at their lower ends to the lower portions of the uprights II-respectively, and at their 35 upper ends to the cross beam 23. The sheaves 29 and 34 are mounted on the uprights II respectively. The sheaves 30 and 35 are suspended from the ends respectively of the uppermost cross beam I3. The sheaves 3| and 36 are mounted on 40 the outer ends of the shovel arms 6 respectively. 'I'he ends of the cables 32 and 31 remote from the .drums 26 and 21 respectively are secured at 38 and 39 to the uprights II respectively near the upper ends thereof. 45

Bumpers are mounted on the upper ends of the uprights II respectively and extend forwardly of said uprights, against which strike the shovel arms 6, whereby the upward swinging movement of the shovel 2 is limited at the upper rear end 50- of the conveyor trough 4 and at the upper forward end of the discharge chute 5.

Flat springs 4I are secured to the uprights II respectively for engaging the'shovel arms 6 and swinging said armsand theshovel 2 forwardly 55 l over the vertical dead center extending through preventing the shovel from remaining in an upright position, when the drum motor is stopped. and particularly when the tractor is on an incline with its forward end higher than its rear end.

The tractor motor l2 is controlled by the e011-V ventional controller 42 within reach. of` the operator sitting in the tractor seat 22. 'Ihe tractor' braks M are controlled by foot pedals Il. The shovel cable drum motor 25 is controlled by a .controller 46 within reach of the operator sitting in the tractor seat 22. 'I'he tractor is steered by the conventional friction lever 4I for the brakes 44 respectively. f,

'I'he operation of our invention is as follows: The shovel 2 being down in position for shoveling dirt, the operator, -by means of the controller 43, drives the tractor I forwardly until the shovel scoops up a shovel full -of dirt, whereupon the operator, by means of the controller ,stops the tractor and, by means of controller ll, op-

erates the cable-drum motor 25, which rotates the cable drums 26 and 21, and said drums, winding the cables 32 and 31 respectively thereon, swing the shovel 2 upwardly and rearwardly over the vtractor through the conveyor trough l to the upper rear end of said troughV and to the upper forward end of the discharge chute l against the bumpers 40 and springs Il, whereupon the dirt.

is discharged from the shovel over its rear inclined wall 41 into the upper end of the discharge chute 5 and downwardly through said chute into a truck below the lower end of said chute. The operator then, by means of the controller l5, stops the motor 25 and winding drums 26 and 2l, and the shovel 2, assisted by the springs Il, drops downwardly to its lowermost position in front of the tractor.' 'I'he above-described operations are repeated, with said truck following the machine until it is loaded with dirt by themachine. Said truck is then driven away from the pile of 'dirt to a dumping place, and other trucks are successively driven under the lower end of said dise charge chute and loaded by the machine, as required.
